#:It shouldn't be surprising that, when Einstein died nearly 60 years ago, he didn't know ''everything'' that there is to know about spacetime.  Newton didn't know everything there is to know about calculus (Hilbert spaces) or classical mechanics (Lissajous orbits), and Bohr and Schrödinger didn't know everything there is to know about Quantum mechanics (entanglement).  What Einstein knew, at the time, about spacetime was how to give a precisely relativistically correct formula for how matter and energy (and momentum and stress) give curvature to spacetime, which in turn gives rise to gravity.  These equations have been confirmed, with great accuracy, repeatedly.

#:Einstein's equations are known to work for "ordinary" interactions at the planetary and galactic level, but don't work at the quantum level, and may not be fully correct at the deep cosmic level.  The cited article says "Every object there is, from a planet orbiting the sun to a rocket coasting to the moon or a pencil dropped carelessly on the floor, follows its [spacetime's] imperceptible contours."  This is a confirmation of what Einstein said.  The article says that there may be more subtlety to spacetime than was previously known.  Of course this has been hinted at for some time with recent developments in cosmology.  "Breaking relativity" is an unfortunate choice of subtitle.
